Abstract

Though many 3-D sensing systems have been developed for application, they could not work normally in some special environment, such as in water, fog, vapor, etc., as there is the strong interference of scattering light. A 3-D sensing system is presented in view of these problems which is based on laser scanning triangulation, the detecting device is special equivalent slit scanning equipment with high sensitive PMT as a detector. The project works on a designed space difference-frequency scanning technique. The application shows the system's great advantages in adverse scattering environment.
